Problem & Symptom : Are you facing a problem like unable to delete a folder due to a process handle Eg: NBU_VSP_CACHE ( This is created by Veritas Netbackup becoz VSP was configured as snapshot provider )Cause : Such files are in use by a process which is active - which prevents deleting same.

Solution :Use Process Explorer tool ( from sysinternals - Microsoft )Process Explorer shows you information about which handles and DLLs processes have opened or loaded.The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

You can navigate & find the specific file which is handling by some process. right click on same and close the handle.then you will be able to delete the file.

Solution:Below are the steps to try out.1. Run WMIDiag utility & get the detailed report to analyze (available from Microsoft to diagnose WMI problems) - CPU utilization could be more while running it.

2. Recompile all problematic mof & mfl files under” %windir%\System32\Wbem” using Mofcomp.exe - If necessary all such files with those extension using a loop command.

3. If above step is not successful, we have to try repair/rebuild of repository – but that may affect installed applications.-----a) -Repair of Repository option by using below commands – minimal data lose rundll32 wbemupgd, CheckWMISetup rundll32 wbemupgd, RepairWMISetup-----b)-Rebuild by stopping WMI service & Deleting the existing Repository then starting the WMI service again to create a fresh Repository ( might cause application malfunction if application specific objects were existing earlier in repository )
